COMMENT
Stresses above those listed under âAbsolute Maximum
Ratingsâ may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this speciï¬cation) is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.

Vin = V- to V+. Device is in
stand-by mode.
Notes: (1) Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used
as a potentiometer.
(2) Relative Linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a
potentiometer. It is a measure of the error in step size.
(3) MI = RTOT/63 or (VHâVL)/63, single pot
(4) Typical = Individual array resolution.
